RAILWAY SIGNAL-TORPEDO.

Specificationof Letters Patent.

Patented July 7, 1914.

To all whom it may concern Be it known that I, FRANK BUTCHER, a citizenof the United States, residing at Versailles, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Railway Signal-Torpedoes, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to improvements in railway signal torpedoes, andthe object of which is to make a torpedo having a case made from a fibersheet which is folded around the explosive compound and passing the leadrail attaching strip through open ings in adjacent folded ends of thesheet and cementing the folded ends and the rail-engaging strip to thefolded body-portion of the case, whereby an eflicient, durable and cheapfiber torpedo is produced.

In the accompanying drawingsFigure 1 is a top plan view of my preferredform, shown attached to a railroad rail. Fig. 2 is an invertedperspective view of the completed torpedo. Fig. 3 is a sectional view onthe line 3-3 of Fig. 1. Fig. 4 is a sectional view on the line 44 ofFig. 1. Fig. 5 is a perspective view of the case, partially folded, theexplosive container and the explosive, the parts being shown inseparated relation. Fig. 6 is a-perspective view of a modified form ofmy improved torpedo, showing it attached to a railroad rail. Fig. 7 isan inverted perspective view of the modified form. Fig. 8 is a sectionalview on the line 88 of Fig. 6. Fig. 9 is a sectional view on the line 99of Fig. 8. Fig. 10 is a perspective view of the blank of the modifiedform shown in operative positionwith the explosive compound block inposition ready to have the case folded around it.

Referring now to Figs. 1 to 5, inclusive, the case of my preferred formis formed from a fiber sheet 1, which is overlapped at its center, asshown at 2, with the ends of the sheet projecting beyond the explosivewhich is contained within the case or tube 1, thus formed. Preferablythe block of the explosive compound 3 is placed within a tubular fibercontainer 4, and around which the sheet is folded. By reference to Fig.5 it will be noted that after the edges of the sheet have beenoverlapped, the edges of the projecting ends 5 are crimped, as shown at6, to be folded in to form the end 7. The

. I blank sheet has perforations 8, which register when the ends arefolded, as shown at 7. Suitable cement 9 is placed on the body of thecase and thelead engaging strap 10 is passed through these openings, asshown in Fig. 2, the cement thus serving to unite the overlapping ends 7and the strap 10 to the body of the case.

The modified form of torpedo is made from a blank, as shown in Fig. 10,in which the blank has the end flaps 11, which are provided with strapreceiving openings and also the narrow end flaps 13. The blank also hasthe side flaps 14. These side flaps 14 are folded in on the explosiveblock 15, and the narrow end flaps 13 overlapping and extending alongthe ends of the explosive block 15, the end flaps 11 are then closedover the body of the torpedo and overlapped. The rail-engaging strip 16is passed through the openings 12, as shown in Fig. 7, and the end flaps11 are suitably cemented together and preferably the lead strip cementedat 17.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A railway signal torpedo, comprising an explosivecompound and a case therefor consisting of a sheet having its sides andends folded therearound and overlapping each other, the folded endsprovided with alined openings having surrounding walls and arail-engaging strip passing through said openings.

. 2. A railway signal torpedo, comprising an explosive compound, a casetherefor consisting of a sheet having its sides and ends foldedtherearound and overlapping the folded endsof the sheet located outsideof the folded sides, the overlapping ends provided with alined openingswhen folded and having surrounding walls and a rail-engagingstrippassing through said openings.

3. A railway signal torpedo comprising an explosive compound, aninclosing case therefor, consisting of a sheet folded over the compoundwith overlapping edges, the sides of the ends of the sheet foldedinward, said ends of the sheet folded transverse the first-mentionedfolds and over the body of the case and cemented thereto and havingstrip-receiving openings, and a rail-engaging strip passing through saidopenings.

4. A railway signal torpedo, comprising an explosive compound, aninclosing case therefor consisting ofa sheet folded over the compoundwith overlapping edges, the

sides of the ends of the sheet folded in-' sides of the ends of thesheet folded ini wardly, said folded ends restin body of the case andcemented t ereto, and a rail-engaging strap interlocking with the foldedends and securing the same together substantially as shown anddescribed.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
